arduino communication with a android

Hi guys,

I am working on project where I am using an arduino mega and a bluetooth module to send a simple text to the andriod phone. I can build the program but I cant get to send the signal over to the phone. The program structure is such , Once the led is high , the buzzer goes on and the signal is sent out to the HTC phone. Can somebody with a kind soul please help me with my program below.

best regards

#include <MeetAndroid.h>

MeetAndroid meetAndroid;

int buzzer = 48; // Buzzer connected to digital pin 48
int ledPin = 50; // the number of the LED pin 50

// variables will change:
int ledState = 0; // variable for reading the led status

void setup()
pinMode(ledPin,INPUT); // pin 13 led as OUTPUT
pinMode(buzzer, OUTPUT); // pin 48 buzzer as OUTPUT
Serial.begin(115200); // start serial communication at 115200bps


void loop()
ledState = digitalRead(ledPin);

if( ledState == HIGH ) // if ‘HIGH’ was received
digitalWrite(buzzer, HIGH); // turn ON the buzzer
Serial.print(“Door is opened\r\n”); // print the message when the Mega received input from Serial1
delay(5000); // delay 5 seconds
meetAndroid.receive(); // read input pin and send result to Android
meetAndroid.send(digitalRead(ledPin)); // add a little delay otherwise the phone is pretty busy
digitalWrite(buzzer, LOW); // otherwise turn it OFF
delay(1000); // wait 1000ms for next reading



Hey bro, I followed the instructions from the below URL. I dowloaded the software which I was told into my htc phone. I paired it up with my bluetooth. I aint sure whether my program is right. so as to narrow down to the problem. The amarino software helps to retrieve data from the bluetooth itself. I am most probably sure it has to be the program.

Sorry guys,

I wasn't sure that cross posting was a illegal thing. I was just trying to get my options wider.

Do a minute amount of research and verify your phone is capable of the serial port Profile.
